Application April 23, 1947, Serial No. 7 13,2497

(Cl. Mil-402) 3 Claims.

This invention relates to guard devices for use in guarding electric light bulbs, as commonly employed at the end of drop lights or extension cords. More particularly, the invention deals with a device of the kind defined e plo in two hingedly coupled parts, one of which employs a closed wall portion so as to form a shield to shade the light from the e es in the use of t e device. Still more particularly, the invention deals with a device wherein the separate parts are formed with angularly disposed walls to produce in the assembled guard a rectangular end, thus adapting the device for mounting on a surface and retaining the device against rolling or shifting on the surface. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views; and in which:

Fig. 1 is a face view of a guard made according to my invention, with part of the construction broken away.

Fig. 2 is a side view of the structure shown in Fig. 1, indicating one part in open position in dotdash lines; and

Fig. 3 is a plan view of the device as seen in Figs. 1 and 2.

In practice, my improved guard is formed from two primary parts 5 and 6, each part comprising wide side wall portions 1 and B respectively, and a pair of narrower wall portions 5 and It'l The wall portions I and 9 of the part 5 are of solid or closed wall formation to form a substantially U-shaped hood or shield thereof, whereas the walls 8 and II! are of openwork construction, as will clearly appear from a consideration of Figs. 1 and 2, Fig. 1 showing the face view of the wall 8, and Fig. 2 the face view of one of the pair of walls II).

The walls 9 are of greater width than the walls ID, as will clearly appear from a consideration of Figs. 2 and 3 of the drawing. Each part 5 and 6 has an open end wall II and I2 respectively, as clearly seen in Fig. 3 of the drawing. The wall I I has a disc portion I3, to which is secured a suspending hook I 4, note Fig. 2. The hook M has a loose rivet, as at I5, so that the hook I4 is free to turn to diiferent positions on the end wall II.

The walls 9 and II) have overlapping portions, as at I6 and I1, through which are passed rivet pivot pins I8 for hingedly coupling the parts 5 and 6 together, so as to allow the rpart 6 to swing outwardly, as indicated in dot-dash lines in Fig. 2 in assemblage of an electric bulb in the device, Each part '5 and 6 is contracted inwardly or downwardly, as seen in Figs. 1 and 2, and the contracted ends terminate in semi-circular collar portions I9 and 2|], having outwardly extending ears 2| and 22 through which clamp screws 23 are passed in securing the parts together and around a lamp socket of an extension cord. The

ears 2! will be threaded to beengaged by the screws 23. On the other hand, it will be apparent that a bolt construction can be used.

The collar portions I9 and 20 have inwardly projecting parts, as indicated at 24 and 25 in Fig. 2 of the drawing to establish a clamp engagement with the conventional lamp. socket in holding t e parts in position thereon.

With my improved construction, the outer end of the lamp guard will be substantially rectangular in form, as clearly shown in Fig. 3, providing four sides upon which the guard may be supported on surface in controlling the direction of light extending from the guard or the electric bulb arranged thereon. On the other hand,

' the guard may be suspended from the hook I,

as in other devices of this kind.

In all uses, the light from the bulb can pass out through the walls 8, I9, I I and I2, whereas the walls 1 and 9 form a shield to prevent the light rays from passing directly to the eyes of the operator using the device. By constructing the guard of the two U-shaped parts in the manner defined, greater and more practical uses of the guard is provided, particularly in SUDDOIt of the same upon a surface and in directing the light toward the work. It will also be apparent that the parts 5 and 6 have at their upper or outer corner portions 'circumferentially continuous substantially L-shaped strips, as at 26 and 21, which provide sturdy edges for the parts and by reason of the contour of the device, these edges will take up the stress and strain on the device in contacting surfaces in the use thereof.

. Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A lamp guard comprising two elongated substantially' semi-pyramidal parts forming flared and contracted ends on said uard, one part defining a large section and the other part a small section, the flared ends having openwork flat end walls, the contracted ends of said parts terminat ing in flanged semicircular clamping bands, means comprising overlapped pivot portions adjacent the end walls of said parts for pivotally coupling said'parts, means clamping the bands together to support the guard in closed position, said end walls forming a square end on the guard, the end wall of the large section being larger than the end wall of the other part, and side walls of the small section being of openwork construction.

2. A lamp guard comprising two elongated substantially semi-pyramidal parts forming flared and contracted ends on said guard, one part defining a large section and the other part a small section, the flared ends having openwork flat end walls, the contracted ends of said parts terminating in flanged semi-circular clamping bands, means comprising overlapped pivot portions adjacent the end walls of said parts for pivotally coupling said parts, means clamping the bands together to support the guard in closed position, said end walls forming a square end on the guard, the end wall of the large section being larger than the end wall of the other part, side walls of the small section being of .openwork construction, and a hook rotatably mounted .in connection with the larger end wall and disposed centrally of said square end of the guard. 3. A lamp guard of. the class described, comprising two hingedly scoupled substantially semipyramidal parts having contracted and flared 4 ends, one large section part having closed side walls forming a shield thereof, the other small section lpart having openwork side walls, means the contracted'ends of said parts for clamping said parts together for engagement with a support, the walls of the two parts collectively defining a square end at the outer flared end portion of said parts, the flared end of said parts having fiat end walls of openworlr construction, the .openwork end Wall of the large section part having a greater width than the other part, and the hinge coupling of said parts comprising overlapping pivot portions adjacent said end walls.
